The aim of the invention is to improve the representation of the area information by additional background information. To achieve this, the representation of the surfaces (20, 21) are generated in a 2 or 3 dimensional view, at least partially by means of aerial and/or satellite views and the resolution of the air and/or satellite views is varied depending on the density of the traffic route network that is represented.
Description
The present invention relates to a kind of cartographic information methods of exhibiting that is used for navigational system, wherein cartographic information has the face of the vertical view that is used to show the map fragment and is used to show the lines of traffic route network.The invention still further relates to a kind of navigational system that is used to implement method of the present invention.
In the past few years, the navigational system in the special mobile application on automobile has a wide range of applications." location ", " target selection ", " distance calculating " and " goal orientation " these basic functions in disclosed system, have been realized.The numerical map of street network is essential for all functions, and this numerical map is placed usually and is stored on CD-ROM, DVD or the HD.
This in addition displaying can preferably colored map.This map shows on color monitor can realize engineer's scale in about 1 to 8000 to 1 to 16000000 scope according to system.This displaying can help to obtain the overview of the travel route in far away or near zone according to engineer's scale.Simplify by for example terrain information of construction area, waters, forest and rail track this location.
Will be on color monitor in the current guidance system that has a map shows as the information exhibition of map vector.Because image scale is as the data basis, storage, this vector quantization is realized the change of image scale.
Whole information is made up of face, lines and point in this map shows.Go out the zone that to show by the different of face with color marker.Build like this, promptly red expression is often used in the settlement.Blueness is used in the waters and farmland or forest use different green hue to represent.The lines of different in width and color are used to represent different streets, rail track or river in displaying.As the single point of other shape element in other words icon represent so-called POI (destination), for example refuelling station, factory, hotel etc. are filled in the whole map shows.
The face displaying is simplified widely and is therefore very abstract.Just in having high-resolution displaying, i.e. near environment particularly, the do not offer help extraneous information of user location of this displaying.
Therefore task of the present invention is by the displaying of extra background information improvement at the surface information of the map that is used for navigational system.
This task is so finished according to the present invention, i.e. the displaying of the face in 2 dimensions or 3 dimensional views at least in part by the resolution of aerial photograph and/or satellite photo generation and aerial photograph and/or satellite photo according to shown in the variable density of traffic route network.The additional architecture basics information of this photo is for example built profile and greenbelt and is helped the user that cartographic information is delivered in the reality.Significantly simplify guiding thus.Realize perspective view shows by 3 dimensional views.
Owing to use aerial photograph and/or satellite photo as the Back ground Information in the screen navigation system, enlarged markedly the map datum amount that needs.Density by the transportation network that will illustrate has obviously reduced the data volume that needs as the structural parameters of the photo resolution that is used to use.In zone, for example use detailed photo with more background information at megalopolis with high street density.And in uninhabited area almost, for example the area, rural area is used the photo with low resolution and is therefore needed less data volume be used for showing.Use the operable data amount to realize the map shows of enough information thus.
A preferred scheme regulation of the method according to this invention, the resolution of aerial photograph and/or satellite photo changes according to the map fragment that will illustrate.According to circumstances mate the degree of accuracy of showing thus.
One according to favourable improvement project of the present invention in, the resolution of aerial photograph and/or satellite photo also additionally changes according to average resident's number of per unit face.This structural parameters are considered this relation, promptly in the settlement, for example in the city resident's quantity apparently higher than the rural area.
Also consider the average building number of per unit face as another favourable structural parameters.The situation of resident's number is considered in similar front on this structural parameters principle, but the building number of unit plane can directly obtain from aerial photograph and/or satellite photo, and does not need other data source, for example the statistics of residence management office.
The navigational system that is used to implement the method according to this invention has the memory storage that is used for the cartographic information data, be used to handle the processor device of map data information and the display device of the cartographic information data output that is used for handling.In memory storage, the street network of vector quantization and be stored as the cartographic information data as the aerial photograph of surface information data and/or the view data of satellite photo.Wherein memory storage can use arbitrarily, promptly use various optics and/or magnetic storage device.Treating apparatus is with different cartographic information data combinations, thereby generation has the displaying of the integral body of face, lines and point, and then outputs on the display device, for example a color monitor.
In preferred navigational system according to the present invention, memory storage has CD (CD) and/or DVD (digital versatile disc).Also can be stored in HD in addition or arbitrarily on the storage chip.This has simplified the renewal of available data and/or the data when using in another one country or state are changed.
The view data that preferably has the aerial photograph and/or the satellite photo of different resolution according to the memory storage of navigational system of the present invention.This importance according to the relevant range has realized the displaying of different accuracy.
The present invention is elaborated as example by accompanying drawing subsequently.Accompanying drawing illustrates:
Fig. 1 is used to implement the figure of a signal of the navigational system of method of the present invention;
Fig. 2 is used for the common map shows of navigational system; With
A fragment of Fig. 3 aerial photograph and/or satellite photo; With
Fig. 4 is used for the map shows of the use method generation of the present invention of navigational system.
Fig. 1 schematically shows a navigational system 1 with treating apparatus 2.Treating apparatus 2 same storage devices 3 link to each other and handle the cartographic information that is kept in the storage device 3.The cartographic information that is generated by storage device 2, for example then to output to for example be the display device 4 of a color monitor in the stack of the vector quantization map of street network and aerophoto or satellite photo.
To describe method of the present invention in detail subsequently.Figure 2 illustrates the map fragment 5 of the subregion of a megalopolis, is the Han Baoda district in the example that provides.Surface information is by basic two different distinguishing with look.Darker face 6 mark construction areas.Brighter face 7 basic representations nature face, for example farmland and forest.
Accompanying drawing has used different lines 8,9 and 10 in addition, and they represent transportation network.Wide and the road that highlights 8 colour are federal highways, are the less streets of building and use the street of Reference numeral 9 marks, and for example country road or intercity 's enters or export arterial highway.Highway section 10 expression railway or the track circuits that use two kinds of colors alternately to illustrate.
Also be useful on appended drawings form point or the icon of expression POI (destination) in this external map fragment 5.Mark the icon that is used to show the position, refuelling station by Reference numeral 11 like this.Indicate the position on airport and indicate the traffic obstacle position of traffic jam in other words by icon 12 by icon 13.
Fig. 3 illustrates the aerial photograph and/or the satellite photo in an intercity zone.Fig. 3 represents the flow through place and the intensive residential district 15 in a river 14.In Fig. 3, can pick out dissimilar and big or small street 16 equally.
Fig. 4 shows the map fragment 17 of using method of the present invention to generate.The data of aerial photograph and/or satellite photo as a setting data linings map fragment 17 times.The street network of vector quantization also is presented on this background images as detailed information with superposeing.In map fragment 17, can clearly identify highway 18 and other street 19 like this.
Now between single street 18,19, be not only dull face, but can identify the real structure of respective regions.The user also can see whether building 20 or green belt 21 in addition on next door, this street on the display device of navigational system like this.
Also additionally special P OI is marked by graphical dots or icon 22 at last.Corresponding image-region, for example the profile of a building public building is painted pellucidly.Described thus building from shown in environment highlight.And can identify simply.Background information as fruit structure generates by aerial photograph and/or satellite photo, and then this enlarges markedly the map datum in the navigational system 1 (Fig. 1).Must use the image information of different big or small resolution for different displaying engineer's scales.For Germany,, draw the data volume that form 1 is subsequently listed in about 876 scopes of taking advantage of the 632km size.
| Face | 1m resolution | 5m resolution | 20m resolution | 100m resolution |
| 375tkm 2 | 140GB | 6GB | 350MB | 14MB |
Data volume listed earlier is based on a kind of data layout of compression.This is the explanation of example and only is used for rough guidance that the compression algorithm that therefore can depend on use changes.
Can find from these data, when high resolving power, 1m for example, whole data volume can not be stored on the storage medium CD or DVD commonly used.The reduction of resolution directly causes significantly little displaying engineer's scale (50m-5km), cause can't see clearly, unacceptable image.If select identical resolution for whole federal territory, can only use the resolution of every pixel 10m so at this face.
Therefore the regulation according to the present invention is selected according to importance for the resolution of different regions.The density of transportation network is used to estimate importance as structural parameters.Now these structural parameters are covered the important distribution of resolution, use more detailed image information in area like this with highdensity transportation network.Traffic route is seldom arranged in the rural area usually, therefore seldom relevant with navigation information is provided, can only use data thus in these zones than coarse resolution.Therefore keeping browsing the data volume that has reduced the view data that stores under the situation of mass conservation greatly.
The storage capacity that is used for the image display requirement is in such order of magnitude, promptly can be stored in common storage medium for example on the CD.Storage medium by using big storage capacity is DVD for example, and the evaluation of traffic route density also can change, thereby optimal is with storage medium ground storage capacity.
Except the density of population that also can use the relevant range as the street density of structural parameters and/or site coverage as evaluation criterion.Be that this information is Already in the aerial photograph and/or satellite photo as the basis with site coverage as the advantage of construction standard.No longer need extra data source, for example the statistics of residence management office.According to the combination that logically also can use three kinds of structural parameters as significant opinion scale.
